EZ-USB Isochronous endpoints use a pool of 1,024 double-buffered FIFO bytes. The
1,024 FIFO bytes can be divided between any or all of the isochronous endpoints. The
8051 sets isochronous endpoint FIFO sizes by writing starting addresses to these registers,
starting with address 0. Address bits A3-A0 are internally set to zero, so the minimum
FIFO size is 16 bytes.
See Section 8.8, "Fast Transfer Speed" for details about how to set these registers.
